Engaging body 56 is arranged on the position opposed with the engagement section 62 of swivel 51.Engaging body 56 can be arranged for fulcrum with fulcrum 64, rotates between the clamped position represented with imaginary line in figure 3 and retreating position indicated by the solid line.Be the position that engaging body 56 is fastened on engagement section 62 with the clamped position that imaginary line represents, by this engaging, restriction swivel 51 rotates to arrow B direction.Retreating position indicated by the solid line is the position avoiding engaging body 56 and the engaging of engagement section 62, and swivel 51 can not rotate by the restriction of engaging body 56.
In engaging body 56, link and engaging body 56 is rotated and the force body (not shown) of the travel mechanism 58 of movement between retreating position and clamped position and the extension spring etc. towards direction force engaging body 56 to be remained on retreating position.
Travel mechanism 58 such as possesses screw actuator, and when usual, energising is cut off and is the state of closing, and engaging body 56 is maintained at retreating position under the force of force body.In addition, when exception described later occurs, be energized in screw actuator and become the state of unlatching, travel mechanism 58 resists the force of force body and makes engaging body 56 turn to the clamped position represented with imaginary line.
Testing agency 60 is the mechanisms of exception of the loopy moving state detecting step chains 14, and the known mechanism that the exception of the loopy moving state of step chains 14 detects in the mechanism etc. of being reversed by the mechanism such as detecting mechanism that propulsive effort transfer chain 40 disconnects, the moving velocity that detects step 12 becomes overspeed condition, the moving direction that detects step 12 is formed.If testing agency 60 detects the exception of the loopy moving state of step chains 14, then pass through from control part 66 to travel mechanism 58 output drive signal, travel mechanism 58 becomes the state (with reference to Fig. 7) of unlatching.
In such a configuration, passenger conveyors 10 passes through actuating device 22 drived control, and axle drive shaft 23 and the sprocket wheel 25 fixed thereon of actuating device 22 rotate.The rotation of sprocket wheel 25 is delivered to driving sprocket wheel 34 via propulsive effort transfer chain 40, and driving sprocket wheel 34 rotates.Rotated by driving sprocket wheel 34, with driving with together with sprocket wheel 34, sprocket wheel 20a, 20b and S. A. 18 rotate integratedly.Rotated by sprocket wheel 20a, 20b, propulsive effort is delivered to the step chains 14 be engaged on sprocket wheel 20a, 20b, the multiple steps 12 linked by step chains 14 by guide rail (not shown) guiding while between the stopping port and the stopping port of lower layer side of upper layer side loopy moving.
In the running of multiple step 12 passenger conveyors 10 of loopy moving between the stopping port and the stopping port of lower layer side of upper layer side as described above, testing agency 60 detects whether there occurs exception in the loopy moving state of step chains 14.When testing agency 60 does not detect the exception of loopy moving state of step chains 14, travel mechanism 58 is positioned at the state of closedown, and engaging body 56 is positioned at retreating position indicated by the solid line in figure 3.Therefore, step chains 14 and the step 12 not loopy moving by the regulation of engaging body 56.
In addition, when testing agency 60 detects the exception of loopy moving state of step chains 14, anomaly detection signal is inputted from testing agency 60 to control part 66, brake equipment 50 action.That is, if input anomaly detection signal to control part 66, then export control signal from control part 66 pairs of travel mechanisms 58, travel mechanism 58 becomes the state of unlatching.Thus, engaging body 56 turns to the clamped position represented with long and two-short dash line from the retreating position represented with the solid line shown in Fig. 3, is engaged on the engagement section 62 of swivel 51.
If engaging body 56 is engaged on the engagement section 62 of swivel 51, then the rotation of swivel 51 is limited, to the power that the sprocket wheel 20a effect restriction be attached on swivel 51 rotates.
In the brake equipment 50 of present embodiment, swivel mount 52 clamps by the friction member 73 be located at outside the 1st on holding member 72 and the friction member 92 be located in inner retention component 90, and slipper 53 clamps by the friction member 75 be located at outside the 2nd on holding member 74 and the friction member 94 be located in inner retention component 90, is attached on sprocket wheel 20a by swivel 51 thus.Therefore, sprocket wheel 20a is by its force of inertia, resist friction member 73,75, the friction force that produces between 92,94 and swivel 51, the friction force namely produced between its friction member 73 and friction member 92 at swivel mount 52 and clamping and the friction force that produces between its friction member 75 and friction member 94 at slipper 53 and clamping continue to rotate with joint efforts, do not rotate together with swivel 51 and stop at once.Thus, stop along with the action of brake equipment 50, engaging body 56 are engaged to the rotation of swivel 51 on engagement section 62 even if become, the clamp 70 be fixed on sprocket wheel 20a also rotate during a moment, clamp 70 and swivel 51 relatively in rotary moving.
Further, sprocket wheel 20a by the cliding friction of friction member 73,75,92,94 and swivel 51 and slow down (braking), then stop.Along with the stopping of sprocket wheel 20a, the loopy moving of step chains 14 and step 12 is stopped.
As above, in the brake equipment 50 of the passenger conveyors of present embodiment, if testing agency 60 detects the exception of the loopy moving state of step chains 14, then by make engaging body 56 be engaged to be located on the engagement section 62 on swivel mount 52 and to limit the rotation of swivel 51, the loopy moving of step chains 14 and step 12 can be made to stop, can preventing step chains 14 and step 12 from going out towards lower layer side.
In addition, in the present embodiment, sprocket wheel 20a and swivel 51 link by clamping the swivel mount 52 of formation swivel 51 and slipper 53 with friction member 73,75,92,94 by clamp 70, so when limiting the rotation of swivel 51 by engaging body 56, sprocket wheel 20a can not stop the rotation at once, and the cliding friction passing through to produce between friction member 73,75,92,94 and swivel mount 52 and slipper 53 slows down and rotates.Therefore, even if brake equipment 50 action, step chains 14 and step 12 also can be made suddenly not to stop and gently stop, can preventing taking advantage of the passenger on step 12 to fall down such accident and occur.
And, because clamp 70 are by clamping swivel mount 52 with friction member 73 and friction member 92 and clamping slipper 53 with friction member 75 and friction member 94, sprocket wheel 20a and swivel 51 are linked, so easily the area of contact of friction member 73,75,92,94 and swivel 51 is arranged larger, can easily the friction force produced between friction member and swivel 51 be set larger.
And, in the brake equipment 50 of present embodiment, the clamp 70 braked by sprocket wheel 20a separate predetermined distance around the centre of gration of the swivel 51 configured with heart shaped with sprocket wheel 20a and are configured with multiple, can the fastening amount of separately adjusting bolt 77 for multiple clamp 70.
Therefore, about swivel 51, holding member 72 outside 1st, holding member 74 outside 2nd, inner retention component 90, friction member 73, 75, 92, 94 and sprocket wheel 20a etc., even if thickness direction (namely, direction perpendicular to the plane of revolution of sprocket wheel 20a) size have some deviations around the S. A. (circumference of swivel 51) of swivel 51, for multiple clamp 70, also can pass through the fastening amount of adjusting bolt 77 respectively and set fastening force equably around S. A., the friction member 73 that can easily will be located on clamp 70, 75, 92, the 94 clamping formation swivel mounts 52 of swivel 51 and the power of slipper 53 are adjusted to the size of hope.
And then, in the brake equipment 50 of present embodiment, because clamp 70 are around the centre of gration configuration spaced apart of swivel 51, so swivel 51 can be cooled, can swivel 51 is relatively in rotary moving relative to clamp 70 time the heat that produced by the cliding friction of friction member 73,75,92,94 and swivel 51 dispel the heat, the relative in rotary moving of swivel 51 stably can be braked.
Further, in the brake equipment 50 of present embodiment, the S. A. around swivel 51 configures 3 clamp 70, by the 3 places clamping of swivel 51 in its circumference, so can be kept by clamp 70 by swivel 51 simply and reliably.
Namely, if configure two clamp 70 and situation about being clamped at two places by swivel 51 around the S. A. of swivel 51, then when being limited the rotation of swivel 51 by engaging body 56 etc., likely with the straight line that two clamp 70 of clamping swivel 51 are linked for axle and swivel 51 rotates around this axle.
In addition, if configure the clamp 70 of more than 4 and situation about being clamped more than 4 places by swivel 51 around the S. A. of swivel 51, then at swivel 51, holding member 72 outside 1st, holding member 74 outside 2nd, inner retention component 90, friction member 73, 75, 92, deviation is had around S. A. in the size of the thickness direction of 94 and sprocket wheel 20a etc., so be difficult to the friction member 73 by clamp 70, 75, 92, the position of 94 clamping swiveies 51 (namely, the position of swivel mount 52 is clamped by friction member 73 and friction member 92, or the position of slipper 53 is clamped by friction member 75 and friction member 94) be all configured in same plane, generation can not with the clamp 70 of the power of the size of hope clamping swivel 51, likely can not stably clamp swivel 51.
Relative to this, if configure 3 clamp 70 and situation about being clamped at 3 places by swivel 51 as the brake equipment 50 of present embodiment, around the S. A. of swivel 51, then must be configured in same plane by the position of friction member 73,75,92, the 94 clamping swivel 51 of clamp 70, so each clamp 70 by swivel 51 with the clamping of the power of the size of hope, can stably clamp swivel 51.
In addition, in the brake equipment 50 of present embodiment, because the guiding part 82 possessing the sliding surface 82b of face contact on the inner peripheral surface 51a of swivel 51 is fixed on sprocket wheel 20a, so when swivel 51 is relatively in rotary moving relative to sprocket wheel 20a, slided on the sliding surface 82b of guiding part 82 by the inner peripheral surface 51a of swivel 51, the mode that can rotate centered by S. A. 18 guides swivel 51.
And, in the brake equipment 50 of present embodiment, so that holding member 74 outside the 2nd is provided with a pair guiding part 82 from the mode of the circumferential sandwich of swivel 51, and a pair abutting part 96 be located in inner retention component 90 is connected on guiding part 82 in the mode sandwiching a pair guiding part 82.Therefore, when swivel 51 is relatively in rotary moving relative to sprocket wheel 20a, holding member 74 and inner retention component 90 outside the 2nd can be suppressed along with the rotation of swivel 51 to move to the hand of rotation B of swivel 51.
In addition, because guiding part 82 possesses multiple sliding surface 82b slided on the inner peripheral surface 51a of swivel 51, even if so a sliding surface 82b slides and weares and teares on the inner peripheral surface 51a of swivel 51, other sliding surfaces 82b also can be made to slide on the inner peripheral surface 51a of swivel 51 and reduce the exchange frequency of guiding part 82.
